Although Quicker does its best to switch Mobile Data, GPS and WiFi Hotspot with a single click, there are devices / Android versions where these settings cannot be switched directly. In such cases shortcuts to stock settings are available only.

Why no direct switch? Because Android security model does not allow installed applications to change secure system parameters. This is done to protect users from malicious application that can misuse those parameters otherwise.
